Spring Boot can't autowire @ConfigurationProperties

Here is my FileStorageProperties class:

@Data
@ConfigurationProperties(prefix = "file")
public class FileStorageProperties {
private String uploadDir;
}




This gives me saying : not registered via @enableconfigurationproperties or marked as spring component.



And here is my FileStorageService :

@Service
public class FileStorageService {

private final Path fileStorageLocation;

@Autowired
public FileStorageService(FileStorageProperties fileStorageProperties) {
this.fileStorageLocation = Paths.get(fileStorageProperties.getUploadDir())
.toAbsolutePath().normalize();

try {
Files.createDirectories(this.fileStorageLocation);
} catch (Exception ex) {
throw new FileStorageException("Could not create the directory where the uploaded files will be stored.", ex);
}
}

public String storeFile(MultipartFile file) {
// Normalize file name
String fileName = StringUtils.cleanPath(file.getOriginalFilename());

try {
// Check if the file's name contains invalid characters
if(fileName.contains("..")) {
throw new FileStorageException("Sorry! Filename contains invalid path sequence " + fileName);
}

// Copy file to the target location (Replacing existing file with the same name)
Path targetLocation = this.fileStorageLocation.resolve(fileName);
Files.copy(file.getInputStream(), targetLocation, StandardCopyOption.REPLACE_EXISTING);

return fileName;
} catch (IOException ex) {
throw new FileStorageException("Could not store file " + fileName + ". Please try again!", ex);
}
}

public Resource loadFileAsResource(String fileName) {
try {
Path filePath = this.fileStorageLocation.resolve(fileName).normalize();
Resource resource = new UrlResource(filePath.toUri());
if(resource.exists()) {
return resource;
} else {
throw new MyFileNotFoundException("File not found " + fileName);
}
} catch (MalformedURLException ex) {
throw new MyFileNotFoundException("File not found " + fileName, ex);
}
}
}




This gives me error saying : could not autowire no beans of type found.



And here is my project structure :







And when I try to run it, it gives me :


---




APPLICATION FAILED TO START

How can I resolve this?
